Ingredients

Scale
  • 2 ¾ cups (345g) all-purpose flour
  • 1 tablespoon baking powder
  • ½ teaspoon salt
  • 1 cup (225g) unsalted butter, softened
  • 2 cups (400g) granulated sugar
  • 4 large eggs, room temperature
  • 1 tablespoon pure vanilla extract
  • 1 ¼ cups (300ml) whole milk, room temperature (or buttermilk)
  • Gel food coloring in pink, yellow, green, blue, purple
  • 1 ½ cups (340g) unsalted butter, softened (for frosting)
  • 5 cups (600g) powdered sugar, sifted
  • ¼ cup (60ml) heavy cream
  • 1 tablespoon vanilla extract (for frosting)
  • Pinch of salt

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour five 8-inch cake pans or line with parchment paper.
  2. Whisk together flour, baking powder, and salt in a bowl; set aside.
  3. Beat 1 cup softened butter and 2 cups sugar on medium speed until light and fluffy, about 4-5 minutes.
  4. Add eggs one at a time, beating well after each addition, then stir in 1 tablespoon vanilla extract.
  5. Reduce mixer speed to low; add dry ingredients in three additions alternating with milk, starting and ending with dry ingredients. Mix until just combined.
  6. Divide batter evenly into five bowls (about 1 to 1 ¼ cups each). Add gel food coloring to each and stir until vibrant.
  7. Pour each colored batter into prepared pans and smooth tops.
  8. Bake for 18-22 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  9. Cool cakes in pans for 10 minutes, then turn out onto wire racks to cool completely.
  10. For frosting, beat 1 ½ cups softened butter until creamy. Gradually add powdered sugar alternating with heavy cream. Mix in vanilla and salt. Beat on high for 3 minutes until fluffy.
  11. Assemble cake by placing purple layer on plate, spreading about ¾ cup frosting on top. Repeat stacking layers in order: blue, green, yellow, pink, frosting between each.
  12. Use remaining frosting to cover sides and top smoothly.
  13. Refrigerate cake for at least 30 minutes before slicing to set frosting.

Notes

Use gel food coloring for vibrant layers. Ensure all ingredients are at room temperature for best results. Cool layers completely before frosting to prevent melting. If frosting is too soft, chill for 10 minutes and re-whip. For gluten-free or vegan options, substitute flour and dairy accordingly.
